Attaching URL

A cell has a possibility to attach URLs. It can be done by using iFrames and AJAX calls.

In the case of iFrames call, an iFrame will be created inside of a cell, and your URL will be attached as
a separate page (it will have access to your code as you will have control over the content inside of the iFrame).

In the case of AJAX call, the content returned by the server will be placed inside of a div.

a common function used for both methods is attachURL(), the only difference is that the 2nd argument is set to true for AJAX call

to prevent caching in some browsers an extra param like "dhxr0123456789" will be added

loading is async, so to proceed with content, you need to use the "onContentLoaded" event

If you need to make some actions with a cell from the attached page (for example, hide the window by clicking some button on the page or collapse a layout's cell)
this can be done in the following way:
